"First of all he’s a great person. I think his philosophy to live life is already great because he wants to enjoy every day, he wants to be happy and he wanted to take this opportunity to start one more chapter in his life," Luiz said.

The defender has featured in all games in the new season for Chelsea so far and is relishing working under Sarri.

"I think that is one of the most important things in life: when you love to do something, when you’re happy. So, I believe in this philosophy, and then after that he is a great coach," he said.

The 59-year-old's preferred playing style, which sees his team play short, snappy passes, certainly suits the Brazilian.

"He wants to play with the ball, he wants to play with intensity, to work on the details and to give us all the information he can about the next game and the opponent," Luiz said.

"Every week he tries to make the best plan possible for the exact game and this is great because he is working in the best way for the team, for the collective," he said.

If Conte had remained at Stamford Bridge, it is unlikely that Luiz would still be at the club, but the 31-year-old is now one of the club's most important players again.
